4 Claims. (01. 232-41) The invention relates to a bottle trap and more of Figure 1 looking in the direction of the arrows.

This superframe 3| is made fast to clamped therein and another released. the posts [5 and IS in any suitable manner and Figure 2 is a top plan view with the screen is disposed horizontally in parallel relation to casing removed. the frame I0.

Figure 3 is a sectional view on the line 31-8 The rocking shafts 19 are formed with the out- 55 wardly bowed intermediate portions 32 and with these and the said superframe are engaged inherently resilient clips 33 which effect tension upon the jaws 20 when opened and closed.

Adapted to be disposed about the stand is a wire screen housing 34, it extending above the upper ends of the jaws and its frame 35 is separably attached to the bail by cotter pins 36, the top portion of the housing being provided with the openings 31 to permit the introduction of milk bottles 38 between the jaws 20 and the removal of such bottles therefrom when such jaws are in open position.

The bail 30 at its upper handle end 39' carriesa swinging arm 40 loosely supporting a closure cap 4! adapted to fit the mouth of either bottle 38 when placed within the receiver, the cap 4| being shown in Figure 1 of the drawings applied to the bottle and this cap 4| is applicable to a filled bottle when within the said receiver, The handle 39 of the bail 30 projects considerably above the upper end of the housing 34 and thus enables the hand carrying of the receiver.

The size of the jaws 20 and the shape thereof are such as to accommodate a quart size milk bottle Now to permit the receiver to accommodate pint size bottles through a flexible chain 42 connected to the bail 30 there is carried an adapter 63 which can be placed within the receiver onto either of the rings .26 so that a pint size milk bottle will be promptly accommodated in the jaws to be clamped by the same.

In the use of the device an emptied milk bottle is inserted through one of the openings 37! in the housing 34 and lowered between one set of jaws 20, there being two sets of jaws within the housing 33 and both sets are aligned with the openings 3?. When the emptied milk bottle is lowered onto the ring 26 the latter is depressed actuating the links 2| to throw this set of jaws 20 into clamping engagement with the bottle 38. This causes the rocker 21 to swing and thus under its action the other set of jaws will be moved to open position and the ring 26 common thereto will be raised so that when a filled milk bottle is placed within the receiver-and clamped by the open set of jaws the empty milk bottle will be freed so that it can be removed while thefilled milk bottle will be clamped within the receiver. The two sets of jaws alternately operate in the opening and closing thereof for the clamping and unclamping of two milk bottles, the receiver being built adaptable for the reception and delivery of the two bottles. I I

The adapter 43 when not in use is hungoutside of the housing 34 as is clearly shown by full lines in Figure 3 of the drawings while the service of such adapter in its use is shown by dotted. lines in said Figure 3.

The screen housing 34 is a protective casing and eliminates the possibility of tampering with the parts of the receiver for hand operatingthe same. The jaws 20 are automatically operated by the insertion of the bottle 38 in either set of jaws of saidreceiver through one of the openings 31 in the housing 34.

The receiver not only insures security of the filled and empty bottles from theft and protection from contamination but it is also an absolute check upon the exchange of empty bottles for filled ones and vice versa, making it necessary for the householder to deposit an empty bottle in the receiver before obtaining a filled one and likewise for the tradesman to deposit a filled bottle before getting the empty one. 7

What is claimed is: j I

1. A trap for milk bottles and the like comprising an open topped receptacle for receiving two bottles, a rock lever pivotally supported in the receptacle, a set of jaws at each end of the rock lever, each set of jaws being adapted to receive and clamp a bottle, a spider for each set of jaws, links connecting the spider with the jaw of its set for closing the jaw upon movement of the spider, a presser ring for moving the spider, and each presser ring having a link connecting it with the rock lever at the corresponding end whereby alternate operation of the jaw is effected. 1

2. A trap for milk bottles and the like comprising an open topped receptacle for receiving two bottles, a rocking lever pivotally supported in the receptacle, a spider member connected each end of said lever adapted to be engaged by the bottom of a milk bottle or the like, asetjo'f clamping jaw members above each spider for clamping a bottle supported on the spider, links connected between each spider and the clamping members associated above the spiders, said links operable to draw the set of clamping members into clamping position when a bottle is placed on a spider and depressed to its lower position with the rocking arm and thereby elevating the spider 0n the other end of the rocking lever and said elevated lever through its link connection with its associate clamping members adapted to operate the clamping members-to released position and to elevate a bottle supported by the spider to a position for removal from the top of the receptacle. v j '1 y 3. In combination with a trap for milk bottles and the like in accordance with claim '2, an adapter for positioning on each spider comprising supplementing members extending upwardly from each spider for engagement'by the bottoms top of the receptacle and terminating in 'a handle at its upper end, and connecting means between the upper portion of the receptacle and the bale maintaining the receptacle assembled over the bottle receiving and clamping members.v
